Copper and aluminum composite projects to radiator: 
 Copper, aluminum, two materials as raw materials, contact with the heating system water piping for copper, the outer wall of aluminum. Copper is more resistant to corrosion, copper and aluminum heat transfer performance. 
 The kinds of products if the two materials composite good, the heat transfer performance of the two materials, the cooling effect is not necessarily good. The difficulty of manufacturing processes, welding difficult, the appearance of the form of a certain limit, the product quality is not easy to guarantee. Chloride ion and easy formation of copper pitting corrosion; In addition, the sulfate ion oxidation of the copper sulfide, Sulfide presence is also a copper corrosion reasons, electrochemical corrosion potential difference caused by the formation of the weld due to welding and thin brass, which is easy to weld leakage. 
 Copper and aluminum composite Heating: 
 1, copper and aluminum composite heating in addition to the advantages of steel heating itself than steel heating, light weight, better heat dissipation, copper and aluminum composite composite made of two materials, the cavity of brass, and better thermal conductivity outside aluminum fins, so that the red points the heat. 
 2, copper and aluminum composite Heating symbol of elegant, more and more pro-lai of the customer, especially since a lot of heating and villas, which hold water less heat, better reflect the energy saving and environmental protection. Especially now that people realize that saving and environmental protection that the South emerging market demand for heating increasing share of copper and aluminum composite heating market is gradually improving. 
 Copper and aluminum compound: the advantages of 
 Copper corrosion-resistant, fast heat conduction. Shortcoming 
 The quality requirements for copper and aluminum expander composite material and process requirements high, otherwise the gap will appear after thermal expansion and contraction for a long time to use, affecting the cooling effect. Merger called two of the copper and aluminum composite radiator expanding technology, divided into hydraulic expander and hydraulic expander pressure over the General Assembly, but in the production process to produce corrugated products produced on the corrosive impact brass poor quality will result in trachoma, likely to cause water seepage. Copper and aluminum composite radiator in mind when installing the interface to the intensity of the copper material force is too easy to crack.
